Cervelo's S3 climbs, corners, and sprints like a pure road machine—only faster. It's meticulously crafted to reduce drag from head tube to chain stay, employing wide tubing, a rear wheel cutout, integrated seatpost, and an aero fork. Even the position of your water bottles reduces turbulence. Race-ready geometry and the fork's stiff tapered steerer bolster your cornering prowess, while thin seat stays reduce road chatter so you stay fresh for the final sprint. Stiff and fast Mavic Cosmic Elite wheels complement the S3’s already-impressive aero attributes. Smooth, accurate shifting is at your disposal thanks to Shimano Ultegra components and Rotor's 3DF crankset. Powerful Ultegra brakes, 3T's stiff bars and stem, and Cervelo's seamlessly integrated aero seat post round out this speed-hungry machine.
The optimum steerer tube diameter must strike a balance of stiffness and energy absorption. Cervelo has found that 1 3/8-inches is ideal, providing enough added stiffness to ensure precise handling without being too rigid or uncomfortable.
Frames are but one component of an entire system. Cervelo considers your hydration needs as part of the aerodynamic equation. Two water bottles fit in the usual positions: one on the seat tube, one on the down tube. In the standard 2-bottle arrangement, the bottles fit together tightly with each other and the frame, reducing the gaps where turbulence can form for lower aerodynamic drag.
In addition, an extra bottle boss on the down tube creates a new lower position for a single bottle. Using the low position on the down tube saves 14 grams of aero drag, a reduction of about 1.4 watts, compared to a bottle in the usual position.
